AAAAH I'M AN IDIOT HURRR
So the pack I'm throwing together seems to work fine, except for some things that irk me. I've made the choice to include Underground Biomes Constructs in my pack, and while generation seems mostly normal, I'm getting large numbers of GT ores that aren't taking the surrounding textures. It's really minor but it IRKS me. That and the fact that vanilla stone is still generating in occasional blobs.
